SAP Note 28139 - Derivation table ignores offset and length

Symptom:

In CO-PA Customizing, you entered an offset and a field length for a characteristic on the detail screen for the derivation table (transaction KE4K). (That is, only part of the table field entered under "master data field" is supposed to be transferred to the relevant characteristic for derivation.)
In characteristic derivation using the derivation table in CO-PA, the system ignores the offset and length. It always assumes an offset of 0 and the length of the source field.

Cause and prerequisites

Error in Program LKEAAU01. Offset and length are taken from Table NAMETAB without adapting them to the entry in Table TKEAN.

Solution
Corrected in Release 3.0B. In earlier releases, change Program LKEAAU01 (Form RESET_PLAN_DEPENDANT_ENVIRON) as follows (changes are marked with <-- ):

Additional key words

Derivation, CO-PA characteristic derivation, KE4K, V_TKEAN, TKEAN
