I have a formula:
@If(CMref_pkg_id = "";CMpkg_desc;
@IsError(@DbLookup("";"";"CMxref";CMref_pkg_id ;"CMpkg_desc")); CMpkg_desc; @DbLookup("";"";"CMxref"; CMref_pkg_id ;"CMpkg_desc"))
This formula checks for a reference field that executes a lookup to extract thedescription froma previous document. The problem is when the reference is used, the description is generating from the previous document, however I cannot add to the description field in this document. I would like to be abble to use the previous description as the default but be able to add or change it. When I do with this formula, it allows the added changes to this field, but then reverts back to the original desc value from te previous document.
