Re: While I am doing tabmerging for MM01, The following popup is comming.

Hello Murali,

This should be resolved by kernel 7.42 pl 219 or higher.

Related SAP notes:

2213948 - Backend Error Occurred - Failed to set value: readonly - after switching tab on

2211672 - Inputfield in ABAPList does not limit input length

Kind regards,
