Gebruik semafore in SharePoint Designer Workflow Eindelose Loops voorkom

6 antwoorde

It’s possible to cause an endless loop in a SharePoint Designer workflow. A common implementation pattern like this causes the problem:

  • Skep 'n workflow en assosieer met 'n lys.
  • Dui daarop dat dit moet begin op die skep van nuwe items en werk van die bestaande items.
  • A step in the workflow updates a field in "Current Item".
  • Sedert die huidige item verander, die workflow begin opnuut.

Hierdie eindelose lus om te verhoed dat, implementeer 'n eenvoudige semafoor:

  • Voeg 'n tuiste kolom (of kolom om die lys / biblioteek as jy nie die gebruik van inhoud tipes).
  • Steek dit uit die wysig bladsy (maklik om te doen as 'n webwerf kolom via sy eienskappe, nie so maklik as 'n lys kolom).
  • In die workflow, kyk om te sien of die waarde van die semafoor kolom leeg.
  • As dit leeg is, sit dit op 'n nie-leë waarde en voort te gaan.
  • Indien nie, is nie leeg, verlaat onmiddellik.

Dit kan 'n redelik genuanseerde oplossing te word, afhangende van die maatskappy se behoeftes en so meer, maar dit is 'n werkbare patroon wanneer ek dit nodig gehad het.

    Paul,
    Asseblief responsd na hierdie. Is jou oplossing werk as die van die lys-item is meer as een keer geredigeer?

    Miskien is ek mis iets hier, maar dit blyk die eerste keer aan die werk, maar nooit weer.
    Wanneer jy die veld Nie leë, dit sal die uitgang van die secone tyd sy genoem. Dit is 'n goeie.
    Maar wanneer jy dit op die item, sê 15 min later, dan is die veld is nog nie opgestel om nie leeg, dus, dit uitgaan sonder die workflow… mis ek iets.
    I hope I am, as ek nodig het om te werk.
    As 'n FYI, Ek het 'n minder elegante oplossing.
    Eerder as om die opstel van 'n vlag op die item self, Ek skep 'n inskrywing in 'n nuwe lys. Toe het die tweede keer deur, Ek verwyder dit. Wat optree as die vlag, maar ek sou 'n meer elegante oplossing soos indien moontlik.

    Hierdie voorstel 'n stap verder te neem –
    Ek het 'n aparte persoonlike lys genoem Kennisgewings en het 'n kolom vir elke workflow Ek het. Ek het probleme ondervind wanneer die stuur van e-posse – veroorsaak dat 'n lus – and mail bombing my inbox. So now, Ek het die workflow die status van die kolom (met dieselfde naam) Voordat die email gestuur, en dan verander die waarde na die e-pos gestuur word.
