Firming indicator for PurRq in MD4C

Hi Friends,

I have released the material with project stock from Project builder. Then I went and checked in MD4C, noticed an "asterisk" being labelled with Purchase Requistion number. When I press F1 button to read the help document, the following message was displayed.

"The system only sets the firming indicator (*) for manually changed planned orders or purchase requisitions. If a firming indicator is set then the system will no longer change the planned orders or the purchase requisitions".

The "firming indicator" is on, MM buyer is not able to change the data on PurReq like buyer etc because it was firmed.

My question, from where and how this "asterisk" is generated which we can see in MD4C (lower section of the screen). Is it from PS and MM settings. I wanted to get ridoff this one and let me know how to take off.

Let me know if you need more detailed information and shall revert and looking forward to hear from you.

Thanks in advance for your time and effort.

Regards,

PSR
