Hide specified value in selector field

Hi @bguzman43 

You have to override the attribute Location and modify the internal selector to accommodate your new filtering criteria. In the following example I am adding value “ExcuideLoc” which will be used to exclude a specific location:

public class LocationExtAttribute : LocationAttribute
{
	public LocationExtAttribute(Type SiteIDType, Type ExcludeLoc) : base(SiteIDType)
	{
		_SiteIDType = SiteIDType ?? throw new PXArgumentException(nameof(SiteIDType), ErrorMessages.ArgumentNullException);

		Type search = BqlTemplate.OfCommand<
				Search<INLocation.locationID,
				Where<INLocation.siteID, Equal<Optional<BqlPlaceholder.A>>,
				And<INLocation.locationCD, NotEqual<BqlPlaceholder.B>>>>>
			.Replace<BqlPlaceholder.A>(_SiteIDType)
			.Replace<BqlPlaceholder.B>(ExcludeLoc)
			.ToType();

		var attr = new LocationDimensionSelectorAttribute(search, GetSiteIDKeyRelation(SiteIDType));
		_Attributes.Add(attr);
		_SelAttrIndex = _Attributes.Count - 1;
	}
}

Once that is implemented you need to replace the current attribute on the field LocationID with the new attribute:

[PXMergeAttributes(Method = MergeMethod.Replace)]
[LocationExt(typeof(InventorySummaryEnqFilter.siteID), typeof(LocationExtType.b_INV), Visibility = PXUIVisibility.Visible, KeepEntry = false, DescriptionField = typeof(INLocation.descr), DisplayName = "Location")]
protected void _(Events.CacheAttached<InventorySummaryEnqFilter.locationID> e) { }

Note that I am passing typeof(LoccationExtType.b_INV) which is a standard constant I defined.

You can find the full example here:

Removes a Location named "B_INV" from the list of locations based on a selected warehouse (SiteID) (github.com)

You can write directly the query using PXDimensionSelector attribute, but will change the original idea of having all encapsulated within the Location attribute implementation.

Hope this approach helps.
