I'm inserting records into the database via a custom app.  When I insert a PO into BKAPPO_BNB, and a line item into BKAPPOL_BNB, the "Line Items" button does not display when I view the PO in DBA (version 2002.4 with ISTS Update 1/16/04), yet hitting TAB twice will display a list of line items, which has my item in it.  When I insert the PO header, I set the BKAP_PO_NL to the number of lines that I inserted.  Is there another field that I need to fill in order to get the button visible?
 
Peace,
Phillip

P and S are the 2 valid entries - for Purchase and Service type POs.
