The Timestamp function operating on a embedded function in a single statement will fail with an error message:
TIRM149E: Error occurred in AllFusion(r) Gen supplied function: TIRFTSC TIRM137E: Input date was not a valid date
When it is required to have a single action diagram statement where the Timestamp function operates on a embedded function e.g.
SET exp testws timestamp_att TO timestamp(FindReplaceString(exp text_att1 ,... ,...))
The embedded statement should be split into two separate statements as follows:
SET exp testws text_att2 TO (FindReplaceString(exp text_att1 ,... ,...) SET exp testws timestamp_att to timestamp(exp testws text_att2)
