Related Items on Blanket Order type

​@Colin MacMillan When Blanket Orders were originally implemented, the focus was on delivering the core functionality first, so support for Related Items was not included at that stage.

If this would be useful for your business scenario, please feel free to submit a product idea or create a support case so the request can be reviewed and tracked.

 In addition to the above, Blanket Orders are primarily designed for planning and release based ordering rather than interactive item selection, so features like Related Items  are not included in that workflow. As a workaround, some customers use standard Sales Orders for item suggestions or handle related item logic outside of Blanket Orders depending on their process.

In Acumatica ERP, the Related Items feature is not enabled for Blanket Order types by design. Blanket orders are intended to act as long-term agreements or contracts, where quantities and pricing are defined upfront and then released later into standard sales orders. Because of this, interactive features like Related Items (which are used for upsell/cross-sell during order entry) are not applied at the blanket level.
