Ability to update start/end dates on Production Order Details

HI @ldancziger  

The start date and end date, which are system-maintained values. Based on the scheduling settings, the system will schedule the production order and determine the start and end date.

The only way that I found to change them is on the Production Order Maintenance, You can select Scheduling Method: User Dates and adjust them there. The actual Production Order will not allow you to change the dates. 

I guess it is not possibel! But I also think this is correct. I think it makes no sense to change manually a Start or End Date of an single work order. It should always be the target to setup the systen in the right way, that the system will do automatically the start and End date scheduling for several work order based on availabel capacity. In this case nobody has to do manual actions 😉

@TimWehrle32 I understand what you are saying, but we do want each operation to have different start dates (obvousally within the date range of the start and end dates of the work order) so every department working on this work order knows when they are needed to start working on it.

I understand the target should be to be automated, we can set these new dates based on our company rules from teh API integration. 

@ldancziger understand. So seems to be that you schedule ouside ERP in 3rd- party tool and give the schedule dates back to Acumatica (but into operations)?! Interesting szenario! I have no experinece on that process. Let me know if you will find a solution 😀 Thx. a lot. 

@TimWehrle32 Thanks 

If anyone knows if there is a way (or confirm there isnt...) would be greatly appriciated

Thanks @Debbie Baldwin for jumping in. im not quite sure what Infinite/Finite scheduling is but i guess you are confirming that with basic Acu functionality its not doable. 

This has come up numerous times with clients who need to manually set the operation dates. 

Curious thread…

I’m struggling with the general scheduling method, the whole Infinite Scheduling and Finite Scheduling doesn’t fit our needs.

Our needs : Capacity based scheduling that accommodates parallel scheduling ( hopefully I’ve used the correct terms ) All of this is currently available in a system I designed many years ago and continues to run quite well but we’d like to move as much of it as we can into Acumatica, for a whole range of reasons though mostly for financial reporting.

At this moment, via a very basic customization, I’ve managed to make the Start Date and End Date available for manual data entry and have extended the Manufacturing end point to include AMProdOper

Using Postman, I’ve been able to illustrate that I’m able to insert and update records within the AMProdOper.

Is there a way to simply disable the scheduling function all together? Doing this might open the doors to many other users who can figure everything out on their own using their own preferred methods and make a lot of people happy.

Thoughts? Insights? ;-)

We also have a need to manually set operation dates.  We do utilize the infinite scheduling calculations (with queue times added) to make the operation dates reasonable for our manufacturing process.  However, we have a need in our Service business to manually set operation dates, as this business unit shares a few work centers with Production, and we manually slide in those operations as we have capacity in Production.  We will want to manually set the dates of the operations in our Service production orders.

I would think if you set a Scheduling Method of User Dates, it should open up the Operations to be manually set.

@ldancziger I will give a brief explanation of infinite vs finite scheduling:

• Infinite scheduling of a Production Order assumes there are NO OTHER production orders in your shop.  So you could theoretically schedule 50 widgets to be completed on the same day when really your shop is only capable of 1 per day.  MRP and Production Orders (without APS module) uses infinite scheduling.
• Finite scheduling looks at your shop’s capacity and tells you when your shop is able to produce the 50 widgets based on your production calendar (no overtime), crew size, efficiency, etc.  So it will spread out the completion dates of the production orders over 50 days in my simple example.  APS or 3rd party module is required for this.

I created an idea to allow manual adjusting of operation dates:

Feel free to upvote if you have this need!

Hi @Debbie Baldwin,

If Acumatica Scheduling is not being used, is there a problem with modifying these fields in the code to allow them to be edited manually?

I’m also curious about this. The APS isn’t something we need, but being able to modify this dates would be hugely helpful for us.

You should be able to create a customization to enable the dates on the operations, but they really should only be enabled if the production order is using the User Dates Scheduling Method.  With any other Scheduling Method, the dates could move based on changes to the production order (at least with infinite).

​@EdGriffiths49 Were you able to create this customization?  We build fire trucks that take many months to complete and have workers across several Operations working on these trucks at the same time.  Parallel scheduling of these different operations, with different offsets for material requirements, is required for us to succeed.  Thanks in advance for your help.  

​@JYoungMBW I haven’t created a customization for this, but I believe other customers have.  If you are updating the dates via an API, we added an enhancement to do this in 25R1.  Thx Ed
