Hi Ringo,
thank you for your answer, I will definitely try out alternative a); but b) seems to be the nicer version.
POC_TIMESTAMP is standard SAP; the data type is DEC 21 with 7 decimal places.
Also, there is a output characteristic defined which limits the output length to 26 with a specific conversion routine. Is it possible that this could also be part of the problem?
Best,
Dominik
