Memory exhausted when reading files into LSMW

When handling exceptionally large files, LSMW will sometimes throw an error like this one returning a mysterious "Return code = 14" instead of declaring that the source data is too large to read into memory. The 14 comes from the GUI_UPLOAD function throwing an error when it runs out of memory because the EXCEPTION for dp_out_of_memory is assigned to 14 in the /SAPDMC/SAP_LSMW_READ_FORMS include. 

Error when uploading file (return code = 14) Message no. /SAPDMC/LSMW_OBJ_070010

The easy solution is to break the source data into multiple, smaller pieces that can be read into LSMW without throwing this error. Try breaking the file into halves or quarters in order to prevent LSMW from running out of memory during the read.
