HFM 11.1.2.2 : data loading error

hello all,

we have migrated from EPM 11.1.1.3 to EPM 11.1.2.2.

our relational database is oracle database.

while up-gradation for HFM we had issue while configuring HFM application.

so we created new HFM application manually.in EPM 11.1.2.2

now we are not able to load data to newly created HFM application.

1. we extracted data from epm 113 in .dat format, but when tried to load it in new HFM application, it is unable to find members for Custom1 dimension.

2. when we tried to load data through excel file, it is showing error as ""

  

any idea ,

is there any changes between .dat file in epm 113 and epm 122
