Obrigado Daniel pela resposta. Consegui fazê-lo funcionar usando um loop while.
p = 0
rowValue = session.findById("wnd[0]/usr/subSCREEN_3000_RESIZING_AREA:SAPLBUS_LOCATOR:2036/subSCREEN_1010_LEFT_AREA:SAPLBUS_LOCATOR:3100/tabsGS_SCREEN_3100_TABSTRIP/tabpBUS_LOCATOR_TAB_02/ssubSCREEN_3100_TABSTRIP_AREA:SAPLBUS_LOCATOR:3200/subSCREEN_3200_SEARCH_AREA:SAPLBUS_LOCATOR:3211/subSCREEN_3200_RESULT_AREA:SAPLBUPA_DIALOG_JOEL:1060/ssubSCREEN_1060_RESULT_AREA:SAPLBUPA_DIALOG_JOEL:1080/cntlSCREEN_1080_CONTAINER/shellcont/shell").RowCount
while p < rowValue: part=session.findById("wnd[0]/usr/subSCREEN_3000_RESIZING_AREA:SAPLBUS_LOCATOR:2036/subSCREEN_1010_LEFT_AREA:SAPLBUS_LOCATOR:3100/tabsGS_SCREEN_3100_TABSTRIP/tabpBUS_LOCATOR_TAB_02/ssubSCREEN_3100_TABSTRIP_AREA:SAPLBUS_LOCATOR:3200/subSCREEN_3200_SEARCH_AREA:SAPLBUS_LOCATOR:3211/subSCREEN_3200_RESULT_AREA:SAPLBUPA_DIALOG_JOEL:1060/ssubSCREEN_1060_RESULT_AREA:SAPLBUPA_DIALOG_JOEL:1080/cntlSCREEN_1080_CONTAINER/shellcont/shell").GetCellValue(p, "PART")
print(part)
p+=1
Saudações,
