Adding mobile phone field to ACC_SRES_COMM

Hi all,

I am trying to add a new field to the ACC_SRES_COMM fieldgroup using the CRMC_BLUEPRINT_C transaction. The field I want to add is the mobile phone field MOB_NUMBER from ADR_DETAIL_COMM_DATA_CAM1.

I always get an error saying the field is not a field from the structure CRMT_BSP_SEARES_PHARMA.

Do I have to extend the structure??

Kind regards

Francisco
