how to validate flatfile record size ?.Actually i am having fixed length flat file which contains Z,V,B record identifiers those records are 55 bytes size. if any record identifier records will come more than 55 bytes in that file . it shouldn’t accept. in this case where to validate?
using above scenario i created flatfile dictionary and flatfileschema
for that file . But in flatfile dictionary , property panel of record identifier it is showing validate option -->conditional operator in that if i try to give %Z<=55% it is not accepting. it is showing as invalid conditional format
how to validate records size?

You have to use Format Service and do perform the validation and reference that in the dictionary/schema.Please check the FlatFile Adapter User guide or use search functionality in this forum.
