0CRM_SALES_CONTR_I sub items are not coming into DELTA

Hi Experts,

we are using 0CRM_SALES_CONTR_I Data souce in our project.

the issuse is while we running full load from RSA3 in crm system we are getting all items and subitems data  related to service contract number,

But if we are running in Delta,  subitems data related to main items is not coming in delta.

we have checked in RSA7 in CRM Systems, main items data are coming fine in RSA7 but subitems data related to main items is not coming into RSA7 Also.

we need to get sub items data also in RSA7, please help on this, how to get sub items data also in RSA7?.

Please see the below screen shots for your reference.

in the below screen shot Sub items 110,210,310,410  records are coming fine

So for same Contract number (5000187023) ID DELTA is not fetching Sub-items (110,210,310,410 etc) records.

Thanks,
