After the last test today we discovered a strange thing:
Taking a look into our PSTA table (the table were the extracted data will be saved) we saw that the column "TIMESTAMP" is set wrong:
"0FI_GL_14" is okay (Filled column "TIMESTAMP") but "0FI_GL_10" is wrong (Contains "0") Same for "3FI_GL_XX_TT" (Wrong) and "3FI_GL_XX_SI" (Correct).
