Issue in activating Extended CDS View

[Ramu7]

Hi Team i am traying to extend the standard view NSDM_V_MARC.

My syntax is as below.

@AbapCatalog.sqlViewAppendName: 'YCL_COBL'
@EndUserText.label: 'Extension view for Append MM_APP_MSEG'
extend view NSDM_V_MARC with ZNSDM_V_MARC_EXT
{
zzdanger,
zztop_stock,
zzstabl,
zzplan,
zzrmatn,
zzdmatn,
zzimatn,
zzid_repa,
zzqs,
zznivq,
zzid_imma,
zzcd_gest,
zzdur_moy,
zzpomatnr
}

But while activating the same i am getting below error.

Internal exception raised (VIEW DEFINITION AND EXTEND DO NOT FIT TOGETHER )

Your help be really appreciated.
