I am having the following inconvenient when inserting a custom field on a DAC extension, with Acumatica 17.202.0016 and 18.103.0022 version. In both versions I followed the next steps:
1) Created a "Usr" field "UsrCustomString", on the Opportunities page CR304000, followed by creating its controls and publishing the customization project.
Creation of "UsrCustomString" field
2) Then I selected an existing Opportunity and assigned a value in the new field.
Updating record with new value
Checking in DB the updated value
After doing this, I noticed that after navigating to the next record and then selecting back the OpportunityID "OP000368", the custom field shows blank. The same happens after pressing the cancel button.
I tried this sequence in the Cases page "CR306000" and it worked correctly. It seems an issue related to the CROpportunity DAC.
