Dear Ravi,
Thanks for your quick reply. I tried your suggested combination, but it is still not working. Actually, in derivation step i used derivation type "assignment" for one to one cost center, fund center combination. It is working fine with numeric cost center, but not working with alphanumeric cost centers.
for temporary solution of this issue, i created another step in my derivation strategy with derivation type "Derivation Rule". In this rule i set all alphanumeric cost centers as source field and same as fund center Target field. in this way it is working fine.
My question is, why it is not working derivation type "assignment" any suggestion please ?
Regards,
Kashif
