For Attribute mapping "Interface Table Data column" not showing you extension column in Siebel Tools

Issue with EIM mapping extension column without Mapping wizard.

Suppose you have to create extension column X_USERID in S_ASSET and EIM mapping with EIM_ASSET.

1) Create extension column X_USERID in S_ASSET.
2) Create extension column X_AST_USERID in EIM_ASSET.
3) Create Attribute mapping in EIM Interface table in tools.

While creating record in EIM interface table, drop down list for "Interface Table Data column" not showing you extension column.

In this case, check if EIM Processing Column Flag  is checked, After unchecking the flag, the column showed in the drop down list, and the attribute mapping could be created.
