All characters are not writing into Application server using OPEN DATASET

Dear all,

I'm trying to write around 1400 characters into CSV file using OPEN DATASET. But only around 1023 characters are writing into CSV file using OPEN DATASET. Please find below ABAP code I'm using

Data: lv_line(3000) type c.

OPEN DATASET lv_file FOR OUTPUT IN TEXT MODE ENCODING DEFAULT.

      CONCATENATE lv_customer_line+0(550)

                                lv_address_line+0(l450)

                                lv_register_line+0(400)

             INTO lv_line.

TRANSFER lv_line TO lv_file.

In the above code, each variable contains record. Also, my requirement is that contents of CSV file should not be separated by any tab deliminator or ';' etc.. Due to this reason, I didn't use SEPARATED BY in above code.

After writing into Application server, only 1023 characters are coming after downloading into CSV file. I've used CG3Y tcode to download CSV file from application server.

Could you please let me know how can I write whole character'1300' into CSV file ?

Thanks in advance,

Dipesh
