I have a FCMP step that ads a conditional format to a spreadsheet.  It works great in traditional SAS, but in Enterprise Guide it returns the errors: ERROR: Unable to publish program for foreign language execution. ERROR: Error reported in function 'python:PUBLISH' in statement number 4 at line 10531 column 5. Here is the code: proc fcmp; declare object py(python); submit into py; def MyFunc(arg1,arg2): "Output: MyKey" from openpyxl import load_workbook from openpyxl.styles import Color, PatternFill, Font, Border from openpyxl.styles.differential import DifferentialStyle from openpyxl.formatting import Rule from openpyxl.formatting.rule import FormulaRule, ColorScaleRule, CellIsRule wb=load_workbook(filename=arg1) ws=wb.active red_fill = PatternFill(bgColor="FFC7CE") dxf = DifferentialStyle(fill=red_fill) r = Rule(type="expression", dxf=dxf, stopIfTrue=True) r.formula = ['$D4<>$E4'] ws.conditional_formatting.add("A4:E100", r) wb.save(filename=arg2) endsubmit; rc=py.publish(); rc=py.call("MyFunc","c:\temp\temp.xlsx","C:\TEMP\ActionDatesQC_2020.xlsx"); run; I have attached the spreadsheet it is modifying.   My system environment paths are working for traditional SAS, is there a different place they need to be set for EG? MAS_M2PATH = C:\Program Files\SASHome\SASFoundation\9.4\tkmas\sasmisc\mas2py.py MAS_PYPATH = C:\Program Files\ArcGIS\Pro\bin\Python\envs\arcgispro-py3\python.exe I know that is an unusual path for Python, but I hope to start calling ArcGis functions in the future. ...
