SAP Error Message - Details

• Message type: E = Error

• Message class: 29 - Bills of Material

• Message number: 049

• Message text: A change number was entered, so the revision level is ignored

What causes this issue?

You want to change or display a BOM and have entered both a change
number and a revision level.
The revision level is an additional identifier for the change status of
a material with reference to a particular change number.
If you enter a change number, the system determines the
<LS>valid-from</> date from the relevant change master record.
In this case, the system ignores the revision level, even if the change
number and the revision level do not refer to the same change status of
a material.
