Create a new fields in CRM_ORDERADM_I using Append Structures

Hi ALl,

Now we have reached the limit of adding new fields in  CRMD_ORDERADM_I table using AET. Now our requirement is to add two new fields in CRMD_ORDERADM_I only. No need to enhance any other BDOC structure.

Can we add new fields using Append Structures into table CRMD_ORDERADM_I ?

Accordingly i have enhanced structures in CRM_ORDER_READ and CRM_ORDER_MAINTAIN FM .

Can any one pls let me know does this whole scenario affect the CRM performance..

Pls let me know ur valuable inputs ..
