No Authorization for Equipment Category

Hi Experts,

All users are empowered with SAP_ALL authorization in our clients Development client.

However when a user tried to change some equipment master data using TCode IE02 an error message appeared stating that ""No authorization for equipment category A". So we have check using SU53 but nothing was there. then equipment category was changed..Same error message appeared.

And we have used login details of another user with SAP_ALL authorization..but result remains the same

Then our basis admin has created a new role with IE02 and assigned to the user. but result was the same error message.

Then He has removed the SAP_ALL authorization and left only the new role with IE02. User was able to change the Equipment data. However user unable to change the equipment master data with both SAP_ALL and new role.

Appreciate your valuable inputs.

Thanks in Advance
