Dear experts,
we are currently facing a strange issue in our SAP BPC 10.1 NW system. We got several custom DM packages which all include a REPLACEPARAM statement for updating the script logic behind. These DM packages run all well, but, and this is the strange thing, only once. If we execute them a second time, we get the error message attached. The BW transaction ST22 did not receive any error, but the SLG1 shows the following message:

Following the instructions in the message (logoff and logon) does not solve the problem. Deleting meta data cache neither. Any research did not help.
Does anyone of you guys know, how to solve this issue? We are running on BPC 10.1 SP16 and SAP BW SP18.
Thank you in advance,
Karsten
