Hello All,
We checked with SAP and as per them, this is the standard SAP behaviour.
i.e; Whenever a PWO with alphanumeric charecters is created, system by default will take the first 10 digits in it and will update in the storage bin field of the outbound delivery. But if a PWO is having only numeric charecters, then it will only take the last ten digits into the storage bin field. We have done a code change to compare the bins based on the PWO number during goods issue. This had resolved our issue.
Thank you all for your commnets.
