[fw-bot]

documentation task card: https://www.odoo.com/odoo/my-tasks/6061325

key change @ lines 133, 136, 149:

• update options list and example to reflect functionality. they were redundant, i.e.:
  • generate so said "generate so when so confirmed" → "generate so when po confirmed"
  • generate po said "generate po when po confirmed" → "generate po when so confirmed"
  • second example was for wrong option, generate so → generate po

other changes, accepted vale suggestions:

• avoid "your"
• avoid plural "(s)"
• avoid smart quotes

note:

• this is just a quick fix requested by a BSA, not a full article refresh.
• follow-up to same bsa's request: [IMP] general companies: inter-company transactions fix #16918
