Hi Mark,
Actually I am not posting a Workorder.
Also I have made sure that the Object which I dealt with was not removed accidentally (Background sending and Client removal step) because of the action step sequence.
I will summarize the problem again.
Let's say that I have a subaction step under the Standard "transmit" action that loops over "ZCOLLECTION" Collection which contains collection of "ZOBJECT".(This Object contains one "External Data Property" along with other Object properties).
Inside this Subaction I have one transaction step which is mapped to "ZTRANSACTION" and this is a Edit transaction for "ZOBJECT". This particular transaction updates all the properties of the Object except the "External data property". In this case while applying the transaction I m getting the error which I have attached in the previous reply.
This behavior occurs even if "ZOBJECT" doesnt have any "External data property" and some of its Child Objects say "ZCHILDOBJECT" contains an "External data property".
Regards
