CRM to PI interface via CRMXIF_IBASE_SAVE01 is failing at SM58 with "Basic Type unknown error"

Hello Experts,

          I am sending an idoc from CRM to PI, It is getting successful in CRM side, but it is failing at ALE layer in SM58 with the error "Basic type 'CRMXIF_IBASE_SAVE01' is unknown". Even if we try to import the meta data in PI (Tcode IDX2) it is throwing the same error.

Message Type: CRMXIF_IBASE_SAVE_M

Basic Type: CRMXIF_IBASE_SAVE01

Thanks
