What causes this issue?

The system could not lock replenishment data.
Before the replenishment data (table WRPL) of a customer is changed,
the relevant table entries must be locked to prevent data from
elsewhere being written to the table.
If no material is indicated in the message text, none of the customer's
replenishment data could be locked.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Contact your system administrator, who can analyze and correct the
cause of the error.

Procedure for System Administrators

Find out which processes/programs write to the replenishment data of
the customer at the same time.
In future, try to implement suitable organizational and administrative
measures to ensure only one write access takes place at one time.
