Acumatica移动端IN202501屏幕集成问题求助：选择LotSerialNbr后InventoryID选择器清空导致无法操作

It sounds like you're hitting a common mobile configuration snag where parent selector values get lost when interacting with a dependent child selector. Let's walk through the fixes to get your IN202501 screen working properly on mobile.

Key Issues & Solutions #

The core problem is that the mobile app isn't properly maintaining the InventoryID value when you select a LotSerialNbr, and the selector dependencies aren't explicitly defined. Here's how to fix it:

1. Add Explicit Parent-Child Selector Binding #

Mobile selectors need clear parent field references to retain context. Update your LotSerialNbr field definition to link it directly to InventoryID:

add field "LotSerialNbr" {
  parentField = "InventoryID"
}

2. Enable Immediate Value Commit for Selectors #

Add commitChanges = True to both fields to ensure their values are sent to the server immediately after selection. This locks in the InventoryID value before you interact with the LotSerialNbr selector:

add field "InventoryID" {
  commitChanges = True
}
add field "LotSerialNbr" {
  parentField = "InventoryID"
  commitChanges = True
}

3. Verify Server-Side Selector Logic #

Double-check your custom Acumatica-LotSerialNbrAttribute to ensure:

• The LotSerialNbr PXSelector correctly filters based on the current InventoryID value
• No FieldUpdated or RowSelected events are accidentally resetting the InventoryID field after selecting a lot/serial number

Updated Full Mobile Configuration #

Here's your revised code with all fixes applied:

add screen IN202501 {
 add container "InventoryLotSerialContainers" {
 add field "InventoryID" {
  commitChanges = True
 }
 add field "LotSerialNbr" {
  parentField = "InventoryID"
  commitChanges = True
 }
 add group "Attributes" {
 displayName = "Attributes"
 collapsable = True
 add attributes "AttributesAttributes"
 }
 add recordAction "Save" {
 behavior = Save
 }
 add recordAction "Cancel" {
 behavior = Cancel
 }
 attachments { }
 }
}

Why This Works #

• commitChanges = True ensures the server knows the selected InventoryID immediately, so the LotSerialNbr selector pulls the correct filtered values
• parentField = "InventoryID" tells the mobile app to retain the parent selector value when interacting with the child selector, preventing it from being cleared
• This aligns the mobile configuration with the server-side selector dependencies your custom attribute relies on

If you still see issues after applying these changes, check the DAC field definitions for InventoryID and LotSerialNbr to ensure they have proper PXDBField and PXSelector attributes configured without conflicting logic.
