Proxy to File scenario design issue

Hi Experts,

I am working on a proxy to file scenario. Proxy team wants to send all the data fields in one row separated by a delimiter. Is this possible in PI?

I will ask ABAP team to send the fixed field length data from ECC instead of a delimiter. How would be my PI data structure for proxy if proxy sends all the data fields in one string?

Please help me out

Regards
