Value ' ' of characteristic 0DATE is not a number with spaces

Hi,

I am facing this issue

" Value ' ' of characteristic 0DATE is not a number with spaces "

This error I am getting during the INIT from the ODS ZTO_PUR4 to the cube ZTC_PUR04.

I am trying to do a look up for two date fields from an ODS ZTO_PUR2 to info cube ZTC_PUR04

Please suggest me what should i do in order to overcome this problem.

Thanks and Best Regards,

Varun Raina
