Batch management is not activating in material master

hi,

I had uploaded stock of material using mvt type 561. For this material no batch management is acitve in material master. Now i want to transfer the stock of material to batches. When i am activating batch in material master system giving me following error:

Batch management requirement cannot be changed; choose "Display errors"

Message no. M3530

Diagnosis

The pushbutton Display errors appears only in dialog mode, not in data transfer or in mass maintenance.

Procedure

If this message appears in data transfer or in mass maintenance, and you want to know why the field cannot be changed, access the material in dialog mode using the relevant transaction below, try to change the field as required, and then choose Display errors:

Industry

Proceed

Retail

Proceed

Even when i had made stock nil, then also same error is coming.

How to do this.
