Need more row in FV50

Dear Expert,

My using JV workflow for parking doc, they using t code:FV50.

From Excel to sap, they copy and paste in t code: FV50, BUT it will take only max 10 line item , they cant use FBV1, iN FBV1 form some entries not showing error (even though in FB00 DOC must be complete)

So that can use only FV50, HOW to make more than 10 rows (line item)

IF its FB50, Environ on menu bar- complex posting will get fast data entry no problem. This one not available in FV50

Kinldy give me a solution, how to make more than 10 rows(line item in FV50)

Regards
